Abstract: This article presents a new way of combining simulations performed in MATLAB 21/Simulink with DIgSILENT PowerFactory 2024software, in order to optimize the use of electrical compensators known as STATCOM in modern electrical systems. The main objective is to address instability problems generated by the increasing use of renewable energies, such as solar or wind. The proposal includes a detailed model and highly advanced adaptive control, which allows fast correction of electrical voltage problems in just 18.7 milliseconds, keeping overshoots below 1.8%. This clearly exceeds the requirements of the IEEE 421.5-2022 international standard. The control system uses advanced vector modulation techniques in dq coordinates, resulting in a very high efficiency of 98.2%, operating normally under conditions of ±50 MVAr. Tests show significant improvements in power quality, with a 43.8% reduction in harmonic distortion (THDv) and 62% fewer losses caused by imbalances. The proposed solution fully complies with important international standards such as IEEE 1547-2018 and NERC PRC-025-2, demonstrating its effective use in real and smart grids. This method also has great potential for application in very high voltage electrical systems (500 kV or higher). The study also paves the way for future research on how to further improve real-time communications, achieving very small delays (less than 100 microseconds).
